Abstract
The present invention provides a functional fluid composition comprising:
- a naphthenic bright stock base oil; and
- a Fischer-Tropsch derived base oil.
- a naphthenic bright stock base oil; and
- a Fischer-Tropsch derived base oil.
Description
- The present invention relates to a functional fluid composition for particular use as a lubricating composition in engines operated under sustained high load conditions, such as in marine diesel engines and power applications. More particularly the present invention relates to a functional fluid for use as a marine cylinder oil in marine diesel engines.
- It is to be noted that, although the present invention has been explained below whilst referring to a functional fluid for particular use as a marine cylinder oil, the present invention is not limited in any way to such a marine cylinder oil; the present invention can be equally applied to lubricating composition intended for other applications.
- Marine cylinder oils used in marine diesel engines are subject to particularly high levels of stress due to the fact that marine diesel engines are usually run continuously at near full load conditions at high temperatures and pressures for long periods of time.
- Marine cylinder oils are so-called "total loss" compositions and their purpose is to provide a strong oil film between the cylinder liner and piston rings. If the oil film breaks down under the high operating temperatures and pressure, the internal walls of the cylinder will be subjected to adhesive wear (known as "scuffing").
- Apart form providing a strong oil film between the cylinder liner and piston rings, the marine cylinder oil is typically formulated to provide for good oxidation and thermal stability, water demulsibility, corrosion protection and good antifoam performance.
- The present invention provides a functional fluid composition comprising:
- a naphthenic bright stock base oil; and
- a Fischer-Tropsch derived base oil.
- It has been surprisingly been found according to the present invention that a naphthenic bright stock base oil can be used in functional fluids such as a marine cylinder oil. Although the use of paraffinic bright stock base oil in cylinder oils has been suggested in the past, the use of naphthenic bright stock base oils would have been deemed unsuitable in view of the relative weak oil film and poor oxidation stability properties thereof.
- In this respect it is noted that
WO 2007/003623 A1 discloses a cylinder oil formulation for use in slow speed diesel engines comprising: - (i) a bright stock base oil blend comprising a paraffinic base oil component having a viscosity at 100°C of from 8 to 25 mm2/sec, and a mineral derived residual and deasphalted oil component;
- (ii) a paraffinic base oil component or a hazy paraffinic base oil component; and
- (iii) one or more additives selected from dispersants, overbased detergents, antiwear agents, friction reducing agents, viscosity improvers, viscosity thickeners, metal passivators, acid sequestering agents and antioxidants. However, no naphthenic bright stock base oil has been suggested in
WO 2007/003623 A1 . - There are no particular limitations regarding the naphthenic bright stock base oil as used in the functional fluid compositions according to the present invention. Typically, naphthenic bright stock base oils are residual base oils from naphthenic vacuum residua obtained by refinery processes starting from naphthenic mineral crude feeds (typically, mineral crude feeds having a TAN (Total Acid Number; ASTM D 664) value of above 0.5 mg KOH/g are naphthenic and below 0.5 mg KOH/g are paraffinic); no dewaxing step takes place in the preparation of naphthenic bright stock base oils (contrary to the preparation of a paraffinic base oil in which a dewaxing step is needed). Mineral-derived bright stock base oils are well known and described in more detail in "Lubricant base oil and wax processing", Avilino Sequeira, Jr., Marcel Dekker, Inc, New York, 1994, ISBN 0-8247-9256-4, pages 28-35. Preferably, the naphthenic bright stock base oil as used according to the present invention has an initial boiling point (true boiling point according to ASTM D 2887) of above 380°C, preferably above 400°C, more preferably above 420°C. Also, the naphthenic bright stock base oil preferably has an aromatic atomic content CA (according to ASTM D 3238) of below 2 wt.% (for a paraffinic base oil this is typically above 2 wt.%).

- The functional fluid composition according to the present invention may - in addition to the naphthenic bright stock base oil and the Fischer-Tropsch derived base oil - additionally contain mixtures of one or more other mineral oils and/or one or more synthetic oils. Mineral oils include liquid petroleum oils and solvent-treated or acid-treated mineral lubricating oil of the paraffinic, naphthenic, or mixed paraffinic/naphthenic type which may be further refined by hydrofinishing processes and/or dewaxing.
- Suitable additional base oils for use in the functional fluid composition of the present invention are Group I-III mineral base oils, Group IV poly-alpha olefins (PAOs) and mixtures thereof.
